I have this in the log events, plenty of these: - Connections: accepted >> thus giving me the password prompt - Connections: closed (GetDC failed: Operation successful (0)) I don't know why the "Operation successful" appears(??)...since I got "server closed connection unexpectedly" from the VNC Viewer. No timeout event.

Maybe it could be a virtual memory failure: 900 MB was remaining on the disk, I cleaned it up. But it wouldn't bring the "GetDC failed" event, would it? Sometimes I noticed that Windows has sockets' problems: can't attribute new socket. But this problem is irrelevant here since the other services on the machine were working fine. > You don't really want to run your VNC Server at a higher priority - if you > do that then it takes priority over the programs you're using it to > access, > which almost certainly isn't what you want.

More seriously: if a software is hanging on the system, I'd better kill the process than let it jeopardizing the machine. I guess a higher priority could be helpful. jcn50. _______________________________________________ VNC-List mailing list VNC-List@realvnc.com To remove yourself from the list visit: http://www.realvnc.com/mailman/listinfo/vnc-list
